Update `import` syntax for `web3`

[Spacesai1or]

Is there an existing issue for this?

• I have searched the existing issues

What would you like to say about Web3.js' documentation?

Docs mention user must import web3 using: import { web3 } from 'web3'; when currently the only supported syntax is import Web3 from 'web3';

During the migration in truffle, I had to use the {} syntax, or I would get the TypeError: Web3 is not a constructor error. Please see my comment:
